Progress to Universal Flu Vaccines

Every year, between 250,000 and 500,000 people of all ages die worldwide after getting seasonal flu, partly because few people are vaccinated for it. Flu comes back every year because when you catch it or are vaccinated, your immune system is only trained to identify the flu’s large surface proteins. These proteins change from year …

Leukemia Patients Remain in Remission More Than Two Years After Receiving Genetically Engineered T Cell Therapy

Nine of twelve leukemia patients who received infusions of their own T cells after the cells had been genetically engineered to attack the patients’ tumors responded to the therapy, which was pioneered by scientists in the Perelman School of Medicine at the University of Pennsylvania. Penn Medicine researchers will present the latest results of the …

Lava dots: Rice makes hollow, soft-shelled quantum dots

New “lava dot” particles were discovered accidentally when researchers stumbled upon a way of using molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots. The researchers also found that lava dots arrange themselves in evenly spaced patterns on flat surfaces, thanks in part to a soft outer …

Ultra-High Temperature Ceramics could enable hypersonic planes

HYPERSONIC aircraft that could fly from Sydney to Madrid in less than two hours could be closer to reality following Australian scientific work with clay. Ultra-High Temperature Ceramics are promising materials for hypersonic aircraft parts because they offer good thermomechanical properties under extreme conditions and they do it without compromising the integrity of the overall …

Diamondoids Improve Electron Emitters

Diamondoids are nanoparticles made of only a handful of carbon atoms, arranged in the same way as in diamond, forming nanometer sized diamond crystals. Previously, researchers at the ALS demonstrated the fascinating capability of these tiny little diamonds to act as a monochromator for electrons. In short, a thin layer of diamondoids deposited on a …

George Church outlines a pathway to indeterminant lifespans via Synthetic Biology

George Church is a giant in gene sequencing, synthetic biology and DNA science. In the October, 2012 Discover Magazine, George Church teases with some ideas he has for achieving physical immortality (indeterminant lifespans) via Synthetic biology. George’s idea is to bring in sections of DNA from exotic organisms or genes that are rare for humans …
